Dozens of Soviet planes searched within a full 50-kilometer radius around the river valley for a whole day, but they found no trace of the [***] team. This made the Soviet army very surprised by the mobility of the [***] squadron. The next day, they extended the search area to 100 kilometers, but still did not find the squadron.

The Mulun Soviet Army, which received the news of the destruction of the baggage, urgently dispatched troops to the ambushed battlefield to rescue them, and on the other hand, seized the time and hurriedly organized vehicles to transport the baggage supplies to the front line again.

Three days later, the Soviet baggage troops set out again. This time, the Soviet army was much more cautious and sent a regiment of escort troops, and the whole process was reconnoitred and protected by Soviet aircraft.

Because of the delay in the supply time, the gap in the supply materials needed by the Soviet army on the Western Front was even greater, and the number and type of supplies needed were more than last time, resulting in a large increase in the number of Soviet convoys this time. However, the number of Soviet trucks was seriously insufficient, and 120 of the Mulun military station were burned, and now only 100 trucks remain, and the rest are more than 400 horse-drawn carts collected.

The logistics department of the Soviet Far East Special Army is actively requisitioning trucks from the people, but it will take time to deliver them to Mulun, and the number will not be very large.

This is because, in the past, the Soviet Union did not have any large automobile factories in the country, and could not manufacture cars in large quantities by itself, and their cars were basically purchased from abroad.

After the appearance of the world's first automobile in 1895, the roar of automobile engines was also heard in St. Petersburg, Russia, the following year, the result of the creation of Russian inventors Yakovlev and Freze. However, due to the weakness of Russia's basic industrial system, Tsarist Russia produced very small cars, and before the First World War, Russia produced only 400 cars in total. Moreover, the factories that produce these cars are small and poorly equipped, and strictly speaking, they can only be called car workshops.

Therefore, during this period, Tsarist Russia imported a large number of cars from the West, totaling tens of thousands. In order to meet the needs of the war, the Tsarist Axe began to build 6 automobile factories throughout the country, with a designed annual output of 7,500 vehicles. But before the factories were built, the Aurora's cannons rang out.

In 1924, the Amov Automobile Factory in Moscow produced the first batch of 10 Amov-Φ15 light trucks in the Soviet Union, which really opened the first page in the history of the Soviet automobile industry. The factory was one of six automobile factories built by the old Russian political axe, and although by 1917 only two-thirds of the work had been completed, it was already the fastest of the six. Subsequently, the Yaroslav Plant, built in 1925 on the basis of the Lebedev Plant, began to produce trucks, and in 1927, the newly built Spartak Plant in Moscow began to produce minicars of its own design.

Although the Soviet government attached great importance to the production of automobiles, because of the weak industrial base and the fact that the Western countries hated the Soviet power and imposed a technical and economic blockade on the Soviet Union, they encountered many difficulties in developing the automobile industry and made slow progress. By the end of the 20s, the annual production of Soviet cars was only a pitiful 2,000 units, which was far from meeting domestic needs, and 90% of the cars on the road still relied on imports.

Stalin, judging the hour and sizing up the situation, resolutely decided to take advantage of this long-awaited opportunity, disregarded the terrible economic situation in the country, tightened his belt, and seized the time to start importing and importing modern industrial technology on a large scale from Europe and the United States, so that the Soviet Union's industrial production capacity was greatly increased in a short period of time.

At present, in the Soviet Union, with the help of the American Ford Motor Company, the Gorky Automobile Plant is being built in Moscow, which is later known as the GAS Plant, and plans to produce GAS-A cars, with a planned annual output of 100,000 units. There is also the Amov plant, which is being renovated, with a planned production capacity of 70,000 vehicles, together with the Red Putiro Plant, etc., which form the basis of the Soviet automobile industry.

It's just that far water can't quench the thirst of the near, and it will take two years for these factories to form production capacity on a large scale.

At present, the military trucks of the Soviet army are all imported cars, and the cars used by the Soviet army in the attack on North Mongolia this time are still sufficient by requisitioning a large number of civilian cars.

After losing 120 trucks, Mulun really didn't have that many trucks to use, so he had no choice but to use large trucks.

However, the difference in speed between the truck and the horse-drawn carriage was too large for them to move together. However, the separate operation and the escort force are insufficient. In the end, in order to ensure safety, the Soviets adopted a compromise approach, with 400 large vehicles in front, accompanied by two battalions of infantry, and trucks in the rear, protected by an infantry battalion and a tank company. Every day, the trucks set off first, and the trucks set off again two hours later, and the two teams met for lunch at noon. The same is true in the afternoon, where the two teams camp together. Another cavalry battalion of the puppet Mongolian army opened the way in front and was responsible for searching and guarding along the way.

The advantage of this arrangement is: during the march, if the large convoy in front is attacked, the truck convoy behind can quickly support; If the truck convoy behind is attacked, because the two teams are not far apart, the escort troops in front can also arrive in about an hour.

From the mouths of the wounded soldiers, the Soviets already knew that there was only one regiment of the Chinese troops attacking them, and this deployment would not give the squadron any chance.

Five days later, the Soviet convoy again came to the valley where the Soviets were ambushed, and camped in the valley that night.

The reason why I chose to camp in the river valley is because out of the river valley, there is a long mountain road in front of me and it is very narrow, and it is very inconvenient for large troops to camp. In particular, camping at night in mountainous terrain with complex terrain is more dangerous.

In addition, it is also important to note that the Soviets believe that the [***] team of the last ambush of their convoy cannot have the audacity to stay near the river valley, unless they are crazy.

In the eyes of the Soviet army, the Chinese had only one choice after taking advantage of the sneak attack, and that was to run as far as possible. If the squadron still wants to continue to block the line of communication, then they can only secretly wait for the arrival of the Soviet troops at a suitable ambush in front of them. This wide valley is the safest at this time.

In order to prevent the transport troops from being attacked again on the road, the large Soviet army that stayed in the Great Tamir has already sent a receiving force, and it is estimated that the two armies will be able to converge tomorrow and the day after tomorrow, and the task of the transport troops will be completed at that time.

Despite this, the Soviet escort troops remained quite cautious, and after they camped on the river beach, they divided the carts that unloaded the horses into three groups, and the other three sides were covered by rows of wagons except for the one facing the river. Then, set up a tent behind the cart. On the riverside side are trucks lined up. For safety, the Soviets were not even afraid of trouble, unloading all the ammunition and weapons from the trucks and storing them properly.

Before dark, the Soviets set up six sentry posts 200 meters away from the camp on three sides, each with a tank, to guard the camp. On some carts and trucks, more than a dozen light and heavy machine-gun firing points were also established. Then, thirty to fifty meters outside the camp, bonfires were lit every forty meters, and three squads of Soviet troops patrolled between the fires.

After arranging all this, the camp of the Soviet army gradually quieted down.

As night fell, darkness gradually filled the wide valley, and the dark Soviet camp was surrounded by the glow of silver water and the beating glow of the campfire, and there was no sound in the valley except for the murmuring of water, the rubbing of blades of grass in the breeze, and the crackling of wood bursting in the campfire, and the whole valley was immersed in a peaceful silence.

In the wee hours of the morning, the Soviets, who had been awakened from their slumber and yawning, continued to doze off again by leaning on tanks or sitting around campfires.

At this moment, from the dense forest on the hillside a few miles away, ten small troops quietly appeared and quickly approached the Soviet camp. These small units are none other than Wang Demin's troops.

A few days ago, after successfully ambushing the Soviet transport troops, Wang Demin did not withdraw with his regiment, but quietly took cover in the mountains and forests on the edge of the river valley after making a circle.

As for the reason for this, Wang Demin's explanation is: After a successful ambush, in order to avoid retaliation, it is basic military common sense to evacuate the ambush area far away. However, they are now carrying out special tasks behind enemy lines, and if they want to take them by surprise, they will have to deviate from military common sense and do the opposite. Therefore, quietly staying near the ambush zone at this time was absolutely unexpected for the Soviet army, which is the saying "dark under the lights".

Moreover, Wang Demin did not take a blind risk in doing so. He was carefully thought out.

The mountainous areas in the western part of Northern Mongolia are high and densely forested, and it is too easy to hide their regiment. Unless the Soviet army dispatched a large force to encircle and suppress the mountains on a large scale, it would be impossible to discover them by relying only on aerial reconnaissance by aircraft.

However, now it is impossible for the Soviet army to resort to the method of searching by ground forces. Because the main forces of the Soviet army on the Western Front are in the Great Tamir area at the moment, it is absolutely impossible for them to abandon their established mission and return to search for their regiment. The Soviet army in Mulun only has one division, and they have to defend the Mulun military station and escort supplies, and the troops are already insufficient. At most, a regiment of troops can be drawn.

Fighting in the mountains, that is their strong point, and fighting with a regiment of Soviet troops in the mountains, they will definitely not suffer. Therefore, it may seem dangerous to stay here, but it is actually absolutely safe.

In particular, the Soviets would never have imagined that they would dare to carry out two ambushes in a row at the same place.

For Wang Demin's analysis, Wang Bin, Shi Zebo and others simply admired the five-body throw. It was unanimously agreed to hide in the valley and wait for the arrival of the Soviet convoy. The second and third battalions were also ready to show their hands and be ashamed.

However, the reconnaissance group that stayed in the vicinity of Mulun to monitor the Soviet troops sent back a telegram describing in detail the special escort method of the Soviet transport team, which made Wang Demin, Wang Bin, Shi Zebo, and others very troubled.

In view of the fact that they had completed the task of delaying the advance of the Soviet troops on the Western Front, Wang Bin suggested abandoning the ambush and withdrawing the troops to the western mountains to rest and stand by. Wang Demin was also unwilling to fight this kind of unconditional ambush warfare, and if he didn't let the Soviet army get entangled, it would be worth the loss, so he also agreed to evacuate.

However, Shi Zebo was a little unwilling, and it was a pity that the troops hid in places that the Soviet army absolutely did not expect for several days, and it was a pity that they gave up the second ambush so easily......
